The steelmaking industry uses products made from lime and limestone to facilitate the steelmaking process and to remove impurities in the steel.

This work requires the use of very high quality lime (above 95% CaO) as a cleaning or smelting agent. In lump form, lime rapidly produces alkali flakes with silicon dioxide in the steel batch, ensuring quick removal of sulfur, phosphorous and other impurities in the steel.

Using a mixture of powdered lime and fluorspar to produce low-sulfur steels.

In the metallurgical industry, lime and Dolomite limestone are also added to create slag; Limit melting of furnace wall; Desulfurization, phosphorus; Heat preservation for liquid metal; Protects liquid metal from oxidation

In Non-ferrous metal making process:

Lime is often used in the selection of sulfide ores to make it easier to obtain the required metal. This application is deployed in the lead, gold, nickel, zinc and copper mining industries.

+ Lime used in metal separation process:

Lime is often used in the selection of sulfide ores to help easily obtain the required metal. This application is deployed in the lead, gold, nickel, zinc and copper mining industries.

Lime is used to increase and control the pH in solutions of cyanide reduction in gold and silver. Thanks to the ability to adjust the pH, lime plays the role of maintaining the cyanide solution in liquid form, so it avoids the cyanide from forming gas and escaping into the environment.

+ Lime is used in the treatment of waste containing acids generated during metallization and drying of mines.

In the mining industries, lime is vital in regulating the pH of wastewater from mining and mine drying. Lime adjusts the pH and the waste is filtered from metals and dissolved salts in accordance with environmental protection regulations.
